ToaZZ whom it may comm.-

VVIrrrn, a subject of Great Britain, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Manifold Construction, of which the following is a specification. 7 r

This invention relates-to manifolding and to motor blocks. It is the object of the present invention to obtain the best results in the operation of a motor by reason of an even distribution of the fuel to each cylinder. This is accomplished by a system of passageways cast in the side of the engine block so as to completely conceal these passageways and do away with the several exposed conduits and ramifications that. are ordi narily provided for this purpose in motors where it is sought to get the best results in the distribution of the fuel.

This form of construction not only does away with a large amount of tubing on the exterior of the motor block which may be in the way of some of the other accessories and adjuncts, but it also permits the use of exhaust heating of the passageways without using jackets and additional pipes to convey the exhaust gases to and from the intake conduits.

The motor-block is also provided with an arrangement whereby a certain portion of the exhaust gases are transferred from one side of'the motor block to the otherto heat the fuel gases that are taken into the cylinder. In the drawings: Fig. 1' is a side elevation of a motor block "showing in dotted lines, the intake ports and passageways by which the fuel gases are distributed to the six cylinders.

Fig. 2 is a sectional perspective showing how the fuel gases are distributed through the manifold.

Fig. 3 is a section taken on the line 33 of Fig. 1.

Fig. 4:-lS a section taken on the line H of Fig. 5.

Fig. 5 is a section taken on the line 55 of Fig. 3.

Fig. 6 is a section taken on the line 6-6 of Fig. 3.

The present system of manifolding is intended primarily for a sleeve valve motor, but I do not limit myself to such a motor. The engine block shown in the drawings is 3 1' an engine block intended to use the single Be it known that I, DOnsAY MoCALL sleeve valve that features the Argyle mo- 'tora well known British car. In this type of sleeve valve, the single sleeve valve is caused to take a helical path by reason of ,to be referred to.

Referring to Fig. 1, it will be seen that the intake passage is provided with a flange f to which may be bolted the conduit leading from the carburetor. The intake track is made up of a lower gallery g, which extends across the third and fourth cylinders and terminates in the upgoing fuel shafts it. These connect with the upper gallery 2', which runs across the second, third, fourth and fifth cylinders. The upper gallery connects with 'hree intermediate galleries, which run across the first and second cylinders, third and fourth cylinders and fifth and sixth cylinders. These intermediate galleries are designated 7' and are best shown in Fig. 3. The upper gallery at each end connects with the intermediate point of each end gallery of the intermediate set of galleries. 'The center of the upper gallery connects with the center of the intermediate galler It will be apparent from tracing the path of the fuel gases that the distance of travel to each cylinder is precisely the same. The distance of travel to one port of each cylinder will be slightly greater than to the other port of each cylinder, but each cylinder has one port in the same ratio further distant from the carburetor and consequently the effect on all the cylinders is .uniform.

Seven exhaust ports are provided in the side of the engine block to take care of the exhaust from the 12 exhaust ports. In the third and fifth exhaust passages, a passageway 70 leads down from the exhaust passage and in between the second and third, and fourth and fifth cylinders, res ectively, to the opposite side of the engine look. This is clearly shown in Fig. 6. This supplies the intermediate galleries are heated by the water jackets n. Furthermore, the upper and intermediate galleries are 1n such close a proximity to the engine cylinders that they abstract some of the heat directly from the combustion chambers.

The casting is also provided with breather ports r at each end and these are provided with flanges and tapped bolt holes to receive any suitable fixture to be attached. Suitable tapped holes 8 are also provided for extracting the core material.

From the above description it will be seen that I have providedan engine block casting which on its exterior is very plain and simple, but which contains numerous passageways that are completely concealed, by which I have secured an absolutely unifrom distribution of the gases through the cylinders to afford a uniform performance for each cylinder, and that I have also so associated the intake track with the cylinders that the fuel gases are in a measure heated by the heat of the combustion chambers to gether also with the cooling water and the exhaust gases. No separate conduits, socalled stoves, or other devices are necessary to use either the exhaust gases or the heated water for the purpose of preheating the fuel. This is all taken care of in the engine block by the properly cored passageways. Not only does this eliminate unsightliness due to a large number of tubes, pipes, etc., on the exterior of the engine but it also eliminates numerous joints. gaskets, etc., and a larger amount of clean, clear space is provided around the engine to take the accessories and necessary adjuncts of the motor.

What I claim is:

1. In a motor block, a unit casting providing a motor block having a plurality of cylinders, and an integral manifold comprising a lower gallery, an upper gallery and a plurality of. intermediate galleries, the lower gallery connecting at its ends with the intermediate (points of the upper gallery and the interme intermediate oints of such intermediate gallery with t e u "per gallery.

2. In a motor b ock, a unit casting cored out to provide a block having a plurality of engine cylinders and provided with intake ports at'the sides of the cylinders and to rovide av com lete plural-galleried maniold integral with the sides of the cylinders and delivering into the ports at the sides of late gallery connecting at.

the cylinders, the galleries being arranged to secure paths of substantially equal length to each cylinder, and an engine block headarranged to removably fit on the engine block above the manifold.

3. In a motor block, a single engine block casting cored out to provide a plurality of cylinders having intake ports in the cylinders, a water jacket, and a complete pluralgalleried manifoldleading directly into the cylinder ports all one integral casting, with the water jacket around both the cylinders and the manifold. and the galleries arranged to provide a lower, upper and intermediate gallery of respectively progressively larger number of passages.

4. In a motor block, an engine block casting cored out to provide a plurality of cylinders, exhaust passages, a complete pluralgalleried intake manifold, and exhaust gas jacket around part of said manifold and connected with the exhaust .passages, all united in one integral casting.

5. In a motor block, an, engine block cast-,

ing cored out to provide a plurality of cylinders, a water jacket, a plural-galleried intake manifold, exhaust passages, an exhaust jacket around a part of said manifold and interconnected passages between the jacket and exhaust passages, all'united in a single casting.

6. In a motor block, a casting cored out to provide a plurality of cylinders, w'ater.

jacket, and integral galleried intake manifold having three sets of galleries to provide equal fuel gas distribution, all united in a single casting.

7. In a motor block, a casting cored out to form a plurality of cylinders, a pluralgalleried manifold having a lower exhaustheated gallery connecting'at its ends with an upper water-heated gallery connecting with three int ermediate galleries at intermediate points thereof, said casting having exhaust passageways connecting with the exhaust jacket above referred to.

8. In a motor block, a casting cored'out.

to form a plurality of cylinders with exhaust passages on one side, and an integral plural-galleried intake manifold on the opposite side, said casting provided with passageways running between the cylinders from some of the exhaust passages to the opposite side of the block and to the opposite ends of the first gallery of the intake manifold.

In testimony whereof I have aflixed my signature.
